This invention relates to Va water closet with nushing cistern made in one aggregate. It has been a general desire not to have the water closets made inV diiferent parts, namely the water closet bowl standing on the iloor, and the iiush tank secured on the wall above the bowl and connected with the latter by a pipe, as it has been most usual hitherto, but it is preferred to have the water closets made in one aggregate which may be placed independently in the closet-room or the bathing-room. The requirements on such a water closet aggregate are amongst other the following.

The connection between the water closet bowl and the flushing cistern must be simple and practical, so that a durable and leakage-free connection is obtained without inconvenient boltings and closure devices.

Sufcient large channels must be present be tween the flushing cistern and the closet bowl, so that the flushing water may rapidly and ei'- fectively be discharged into the bowl in order to flush the same eiectively.

The flushing water must be lead in such a manner` that it flushes the entire inner wall surface of the bowl.

The device for effecting the flushing must be convenient and reliable.

All these requirements are fulfilled in a water closet according to this invention.

As an example, a water closetaccording to this invention is shown in the accompanying drawings, wherein Fig. 1 is a vertical longitudinal section of the water closet having all the parts in initial position,

Fig. 2 shows the upper part of the closet in vertical longitudinal section with the seat lid raised and the valve flaps of the flushing cistern closed, the tap being made free to function,

Fig. 3 is a transverse vertical section on the line A-A of Fig. 1,

Fig. 4 is a horizontal section on the line B-B of Fig. 1,

Figs. 5 and 6 show on a larger scale a detail of the movement transfer mechanism between the seat lid and the valves of the iiushing cistern, Fig. 5 being a vertical section on the line C-C of Fig. 6 and Fig. 6 being a horizontal section on the line D-D of Fig. 5.

In the upper part of the water closet 1 there is a flushing cistern chamber 2 the bottom of which is situated somewhat beneath the upper edge 4 of the bowl 3. In the chamber 2 a flushing cistern 5 is partly sunk. The flushing cistern 5 is provided with a resting surface 6 resting on the upper edge of the flushing cistern chamber, said upper edge being situated in the same horizontal plane as the upper edge 7 of the water closet; The lower part 8 of the iiushing cistern then extends down into the flushing 'cistern chamber 2, while the upper part 9 of the flushing cistern projects a distance above the upper edge of the closet bowl. That wall of the lower part 8 of the flushing cistern which is turned towards the bowl 3, is provided with one or more (according to the drawings three) discharge-holes 10 at which clack valves 11 are arranged.

A vertical channel 12 extending through the ushing cistern chamber 2 and being open at both ends, is formed of the faience, and a vertical pipe 13 is watertightly secured to the bottom of the ilushing cistern 5, the lower end of said pipe being situated beneath the bottom of the flushing cistern chamber2. The iiushing cistern 5 is locked to the closet by a nut 14. of the pipe 13, and 'closure at the hole of the bottom of the flushing cistern chamber is obtained by a usual tightening ring. The pipe 13 forms a channel open at both ends which channel extends upwards to the upper part 9 of the flushing cistern and opens above the ,water-level in the cistern when the latter has been lled with flushing Water. y

A segment 17 is attached to the seat lid 16. A rope 30 secured to the lid runs over the segment, down` through the channel 12, round vguidingwheels 18 the supporting member of which is bolted to the bottom of the vflushing cistern chamber, upwards through the pipe 13 and round the wheel 19 to which the rope is secured and the supporting member of which is attached to the upper part of the pipe 13. Then the rope extends down to a cross-piece 20 towhich the rope is adjustably xed. As will be seen fromFig. 3 the cross-piece 20 is provided with threeplates 21 adjustable vertically in relation to the crosspiece. The clack valves l1 are'by chains connected to said plates. Owing to this arrangement the clack valves may be adjusted in such a way,

that one valve will rst be opened and then the two other ones, or inversely, when the flushing is to take place.

As will be seen from Figs. 5 and 6, the wheel 19 is rotatably mounted on a horizontal shaft 22 and provided with a lateral pin 23 adapted to actuate a lever .24 mounted to swing vertically on the supporting member of the wheel 19. In the initial position according to Figs. 1 and 3 a lever 26 of a float operated tap 25 rests on the lever PATENT lorljlhcE I 24. The float 27 is secured to the lever 26 so as to be able to be raised and lowered. Guiding walls 28 (Fig. 4) are formed of the faience, and an overiiow pipe 29 is watertightly secured to the bottom of the flushing cistern.

When the closet is to be used the seat lid 16 is raised from the initial position (Fig. l) to the position shown in Fig. 2. rThe segment 17 will then be swung downwards, wherebythe rope 30 is slackened and the cross-piece 20 together with the valve flaps 11 connected thereto are lowered owing to their weight, so that the valve flaps will close the discharge-holes 10. As the rope 3*() is secured to the wheel 19 the latter will be rotated with the sun, when the cross-piece 20 and the valve flaps are sunk. The pin L23 will be raised, so that the lever 24 is liberated. The lever 26 of the tap which lever rests on the lever 24, will then be lowered owing to the weight of the float, whereby the tap 25 will be actuated in such a manner, that the tap is opened and the water streams into the iiushing cistern. When the water level in the iiushing cistern has raised tc the desired height the oat rises.

Theheight position of the float has been adjusted in such a way that the iioat will then float on the water. At the same time as the float the lever 26 attached thereto also raises and the tap is closed. The desired iiushing water quantity is now in the iiushing cistern and the different parts have the position shown in Fig. 2.

When the closet has been used the seat lid 16 is laid down. Thereby the segment 17 will be swung upwards and causes a pull in the rope 30, so that the valve flaps l1 are raised liberating the discharge-holes 10. The iiushing water collected in the flushing cistern will now stream through the discharge-holes into the bowl 3. The water is led by the guiding walls 28 (Fig. 4) in such a way, that the entire inner surface of the bowl will be effectively iiushed. As the rope 30 is secured to the wheel 19 the latter is rotated contrary to the sun, when the seat lid is laiddown. The pin 23 will then be lowered and acts upon the lever 24, so that the latter again occupies the position shown in Fig. 1 and supports the float lever 26, so that the tap is held closed. In this position `the lever 24 serves as a locking device for the iioat lever. As the clack valves by means of the plates 21 may be adjusted in such a way that they will be opened at different moments, the flushing water is caused to stream first to one part of the bowl and then to another part of the same.

If for some reason the water level in the flushing cistern should raise above the normal height, the excess of water flows through the overflow pipe 29 into the bowl. As the upper end of the overflow pipe is situated lower than the upper end of the pipe 13, no water can iiow down through the pipe 13 and cause leakage on the ioor.

Water closets arranged according to this invention may be made in manywother ways than that described as an example, without departing from the spirit and scope of the invention. For instance the device for transmitting the movement of the seat lid to the clack valves and to the locking lever 24 for the float operated tap may comprise levers or the like.

Having now described my invention, what I claim as new and-desire to secure by Letters Patent is:

l. In combination, a closet bowl, a chamber located substantially at the level of the bowl forming a part vthereof and being in open communication therewith, a stationary flush tank wholly supported by said chamber and extending into the latter, a shoulder on said flush tank bearing on said chamber, and a discharge valve provided in said flush tank.

2. An arrangement as claimed in claim 1, characterized by the provision of means establishing permanent communication between the iiush tank and the atmosphere a lid member for the bowl, a discharge valve for the flush tank, means connecting the lid with the discharge valve, a water supply valve controlled by said connecting means, said connecting means operating, when the lid is lifted into its uppermost position, to close the discharge lvalve and open the water supply valve and, when the lid is closed, to open the discharge valve.

3. An arrangement as claimed in claim 1, characterized by the provision of means establishing permanent vcommunication between the flush tank and the atmosphere a lid member for the bowl, a discharge valve for the iiush tank, means connecting the lid with the discharge valve, a water supplyvalve Ycontrolled by said connecting means, said connecting means operating, when the lid is lifted into its uppermost position, to close the discharge valve and open the water supply valve and, when the lid is closed, to open the discharge valve, and .fluid-tight guides extending through said chamber and the flush tank and receiving said connectingmeans, the guide in the iiush tank extending above the level of the water therein when the flush tank is filled.
